Post on Gnu Radio Companion filtering

[Gary Schafer]

Evening, everyone! Long time listener, first-time caller and all that.

I've been using Gnu Radio Companion for the past, few years. I've been 
compiling notes on how to use use it along the way. I've started posting on my 
website how GRC works (to the best of my ability, as I'm not a programmer). I 
did a few posts on the various ways to make a frequency demodulator in GRC, and 
my latest is on basics of filtering with GRC.

I'm putting together more explainers as I go, time permitting.

Comments, questions and corrections are welcome!
